Application le'd. September 4 1917. Serial No. 189,664).`

To all 'whom t may concern:

Be it lrnown that I, PAUL S. Liirrz, a citir/ien of the United States, residiiig'at Chicago,in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Beds for GainefTableS and Methods of Making Same, of which the following is a specification.

My invention relates to gaine tables and has for its primary object the provision of a satisfactory*substitute for slate beds now commonly used on billiard, pocket billiard and other gaine tables.

Further objects and advantages of my iiivention will be apparent as it is better understood by reference to the following specilication when read in connection with the accompanying drawing illustrating thepreferred embodiment thereof, in which#` The igure is a sectional view of a portion of a table bed constructed in accordance with my invention.

My inventioncomprises a bed embodying I a core preferably of wood which is wholly 'following ingredients in inclosed within a shell, applied thereto in a plastic condition, which when cooledand subjected to pressure becomes dense, moisture proof and very hard, making an ideal bed for gaine tables.

In carrying out my invention I first prepare a plastic composition consisting of the the proportions noted.

Earthy material and lcement 12 parts Asbestos 2 parts Rosin 1-- l2 parts Common' soap 2 parts terial is preferably half andv half. lAllv coarse material is removed. The ground material must be free from moisture and may be dried if necessary. It is heated to a ltemperature of 250 'F'. and is then mixed in any suitable mixing lapparatus with the binder consisting of rosin and commonl soap,

which is previously melted and flieated toa temperature of 250 F. The composition will have vabout the consistency ofiiiolasses and is ready to be cast.

rlhe coreis constructed of seasoned wood strips 5 preferably about seven-eighths of an' inch in thickness vand is slightly .smaller than the dimensions of the bed of the table for which it is intended'. The strips should be tongued and grooved andglued together with a heat withstanding glue and both sides of the strips shouldbe roiglieiiedso thatv will readily adhere the plastic material 6 thereto. i y i, rihe core is centered 'in a frame leavin@r a space of about three-eighthsof an inch, e`

tween the side faces of the core and the frame.. ril`he plastic material is then run into the frame on both sides of the core and around. its edges until the coreis c ompletely4 inclosed, after which it is subjected to 'a pressure of about iifty tons per squarey foot until the plastic material is about one- 4 eighth of an inch thick on each face of the core. rIhe bed is tlieh cooled, removed from the press and placed' in a seasoning press where it remains for at least thirty days before being used.

'The 'frames are constructed of cast ironand are carefully machined so that the infterior dimensions are exactly the Isame as the desired dimensions of the table'` bed.y

They are provided with steam heating lpipes j through which live steam may be injected to :bring the interior of the frame and the core to a uniform temperature of 250 F. before the plastic material is introduced.

The steam is cut O' before the pressing op? eration commences and cold water is subsequently forced through the pipesto cool the finished bed. i

Beds constructedvof the material and in` the matter hereinbefore specified" are found to fill a'. long felt need in the art for a satisfactory bied which is cheaper 'than slate yet has all of its desirable qualities. The Wood ncore is so thoroughly protected by the moisture proof coating that it 'cannot warp or expand or contract under changing atmospheric andI temperature conditions. When mounted on the table it remains perfectly true and level, indefinitely.

Various changes may be made in the forni, construction and arrangement` of the parts without departing from the spirit and scope ofthe invention or sacrificing any of its majterial advantages, the formsv hereinbefore de- ".SC/ribed being merely the preferred embodi- 'rnent thereo I'clairn': v'-1. A bed for game tables comprising a `sore Substantially eoeextensive in area with theare'a of the bed., and a shell completely inclsi'nfr said core and consisting of ahard,

' f uydense' moisture proof composition.

A bed for game tables Comprising a Wood Core substantially (5o-extensive in area with the area of said bed, and a'dense, hard moisture proof shell completely inelosing said core and having a smooth level upper surface.

6. A bed for game tables Comprising a Wood core substantially c'Q-eXtensive in area With thearea of said bed, and a dense, hard moisture proof shell applied to said Core in a-plaste condition and having a smooth level upper surface.

7. A bed' for game tables comprising a Wood eoresubstantially (3o-extensive in area with the area of the bed, and a dense, hard moisture proof shell, inclosing said core and consisting of earthy material, anda bindern Atherefor, said shell having a smooth level `material and a plastic. binder therefor', the

surface of said facing being smooth `and level. i

10f A bed for game tables consisting of a core. of abutting Wood strips adhesively secured together, said core being substantially eo-eXtensive in area with the area ofthe bed,

and a dense, hardlnoisture proof faeing on said core and consisting of earthy materialand a rosin binder therefor.
